Around the A.D. 155, St. Justin Martyr wrote in his Dialogue with Trypho the Jew that the Holy Scriptures teach us concerning Christ,
"'that He became Man by the Virgin so that the course which was taken by disobedience in the beginning through the agency of the serpent, might be also the very course by which it would be put down. For Eve, a virgin and undefiled, conceived the word of the serpent, and bore disobedience and death. But the Virgin Mary received faith and joy when the angel Gabriel announced to her the glad tidings that the Spirit of the Lord would come upon her and the powers of the Most High would overshadow her, for which reason the Holy One being born of her would be called the Son of God. And she replied: 'Be it done unto me according to thy word.'"St. Justin Martyr therefore parallels the Virgin Mary with the Virgin Eve. Just as the word of the serpent bore fruit through the Virgin Eve, so the word of God came into the world through the Virgin Mary. Eve believed the word of an evil angel and death was brought into the world, while Mary believed the word of a good angel and Life Himself was brought into the world.
Now let's look at another passage: around the A.D. 190, St. Ireneus, in his masterwork, Against Heresies, writes,
"Consequently, then, Mary the Virgin is found to be obedient, saying: "Behold, O Lord, your handmaid; be it done to me according to your word." Eve, however, was disobedient; and when yet a virgin, she did not obey.... having become disobedient, was made the cause of death for herself and for the whole human race; so also Mary, betrothed to a man but nevertheless still a virgin, being obedient, was made the cause of salvation for herself and for the whole human race.... Thus, the knot of Eve's disobedience was loosed by the obedience of Mary. What the virgin Eve had bound in unbelief, the Virgin Mary loosed through faith."So again we see the second century fathers contrasting Mary and Eve, saying that the evil done through Eve was undone through Mary.
Now let us look at another text, this one from the beginning of the third century. Around the A.D. 210, the Catholic Tertullian wrote in his treatise, On The Flesh of Christ, that
"...it was while Eve was still a virgin that the word of the devil crept in to erect an edifice of death. Likewise, though a Virgin, the Word of God was introduced to set up a structure of life. Thus, what had been laid waste in ruin by this sex, was by the same sex re-established in salvation. Eve had believed the serpent; Mary believed Gabriel. That which the one destroyed by believing, the other, by believing, set straight."(Source: http://www.cin.org/users/james/files/key2mary.htm)
The Epistle of Ignatius to the Virgin Mary
Her friend(1) Ignatius to the Christ-bearing Mary.
Thou oughtest to have comforted and consoled me who am a neophyte, and a disciple of thy [beloved] John. For I have heard things wonderful to tell respecting thy [son] Jesus, and I am astonished by such a report. But I desire with my whole heart to obtain information concerning the things which I have heard from thee, who wast always intimate and allied with Him, and who wast acquainted with [all] His secrets. I have also written to thee at another time, and have asked thee concerning the same things. Fare thou well; and let the neophytes who are with me be comforted of thee, and by thee, and in thee. Amen.
Reply of the Blessed Virgin to This Letter.
The lowly handmaid of Christ Jesus to Ignatius, her beloved fellow-disciple.
The things which thou hast heard and learned from John concerning Jesus are true. Believe them, cling to them, and hold fast the profession of that Christianity which thou hast embraced, and conform thy habits and life to thy profession. Now I will come in company with John to visit thee, and those that are with thee. Stand fast in the faith,(2) and show thyself a man; nor let the fierceness of persecution move thee, but let thy spirit be strong and rejoice in God thy Saviour.(3) Amen.
Ignatius, and the brethren who are with him, (to) John the holy presbyter.
We are deeply grieved at thy delay in strengthening us by thy addresses and consolations. If thy absence be prolonged, it will disappoint many of us. Hasten then to come, for we believe that it is expedient. There are also many of our women here, who are desirous to see Mary [the mother] of Jesus, and wish day by day to run off from us to you, that they may meet with her, and touch those breasts of hers which nourished the Lord Jesus, and may inquire of her respecting some rather secret matters. But Salome also, [the daughter of Anna, ] whom thou lovest, who stayed with her five months at Jerusalem, and some other well-known persons, relate that she is full of all graces and all virtues, after the manner of a virgin, fruitful in virtue and grace. And, as they report, she is cheerful in persecutions and afflictions, free from murmuring in the midst of penury and want, grateful to those that injure her, and rejoices when exposed to troubles: she sympathizes with the wretched and the afflicted as sharing in their afflictions, and is not slow to come to their assistance. Moreover, she shines forth gloriously as contending in the fight of faith against the pernicious conflicts of vicious(1) principles or conduct. She is the lady of our new religion and repentance,(2) and the handmaid among the faithful of all works of piety. She is indeed devoted to the humble, and she humbles herself more devotedly than the devoted, and is wonderfully magnified by all, while at the same time she suffers detraction from the Scribes and Pharisees. Besides these points, many relate to us numerous other things regarding her. We do not, however, go so far as to believe all in every particular; nor do we mention such to thee. But, as we are informed by those who are worthy of credit, there is in Mary the mother of Jesus an angelic purity of nature allied with the nature of humanity.(3) And such reports as these have greatly excited our emotions, and urge us eagerly to desire a sight of this (if it be lawful so to speak) heavenly prodigy and most sacred marvel. But do thou in haste comply with this our desire; and fare thou well. Amen.
His friend(1) Ignatius to John the holy presbyter.
If thou wilt give me leave, I desire to go up to Jerusalem, and see the faithful(2) saints who are there, especially Mary the mother, whom they report to be an object of admiration and of affection to all. For who would not rejoice to behold and to address her who bore the true God from her(3) own womb, provided he is a friend of our faith and religion? And in like manner [I desire to see] the venerable James, who is surnamed Just, whom they relate to be very like Christ Jesus in appearance,(4) in life, and in method of conduct, as if he were a twin-brother of the same womb. They say that, if I see him, I see also Jesus Himself, as to all the features and aspect of His body. Moreover, [I desire to see] the other saints, both male and female. Alas! why do I delay? Why am I kept back? Kind(5) teacher, bid me hasten [to fulfil my wish], and fare thou well. Amen.
